What are some good secuirty softwares tha ti can use to check local machines that has confidential stuff, like social secuirt number or credit card numbers? As an IT secuirty person, my job is to scan computers for any confidential data and remove them instead of zero writing the hard drive.

Software should also have ability to scan emails, tash cans, hidden files, hash files, or any other method that file might exist that holds the confidential information.

Also, searching and removing would not take into account the "free space", where the information may have existed previously.

Forgive me if I sound dubious, but your request sounds either contrived or ignorant. "Software should also have ability to scan emails, tash cans, hidden files, hash files, or any other method that file might exist that holds the confidential information. " How exactly do you plan on gaining anything useful from "hash files" or encrypted files? Those would fall into the "any other method".

Your request sounds more like "Just tell me how to scan machines for the lucrative info, even if it is protected, he he." Regardless, there is no overall method to search for such information. You can try text pattern matching for existing files.

EnCase® Enterprise Information Assurance Suite would probably fit your needs. It has the capability to "Conduct complete classified spillage clean-up with the only tool that enables automatic, targeted search and remediation." It searches across a wide variety of formats, including mailboxes, word documents, and pdf files.
